BOBBIN-THREAD-SL P?LY HOLDER AND GUIDE.

Application filed May 1,

To all whom it may concern:

Be it known that we, lhlAX GI BERT, a citizen of the United States,residing at Bronx, county of Bronx, and State of New York,

5 THOIvi-AS GUIDE, a citizen of the United States, residing at Brooklyn,county of Kings, and State of New York, and Sono- MON .Kir'rz, a citizenof ltussia, but having taken out his first papers in the United States,residing at Brooklyn, county of Kings, and State of New York, haveinvented a certain new and useful Bobbin- Thread-S-upply Holder andGuide,of which the following is a specification.

This invention is a thread holder so constituted as to render it highlyefficient in supporting a large roll of thread in a position convenientto the bobbin of a machine and embodying means for guiding said threadduring the winding thereof on a bobbin;

large manufacturing establishments, it is the practice to buy thread inrelatively large rolls or tubes which thread is taken from the rolls ortubes and wound on the bobbin as Occasion may require. The thread isdelivered to the factories in the form of large rolls or tubes whichwhen not in use are set on shelves or on the tables of machines untilsuch time as the threading of a bobbin is necessary whereupon the rollsor tubes manually manipulated into position to thread the bobbin andafter the threading is completed the rolls or tubes are once more placedon sh yes or on a table of a machine. The handling of these rolls ortubes loosely, as is the universal practice, causes the thread to becomesoiled and in most larg factories one or more of these rolls or tubes ofthread may he found on the iloer at time. Long before the roll or tubecompletely used, the thread becomes loosened thereon and slips from theend of the roll or tube and becomes tangled in such condition that it isunfit for use and it is not uncommon for wl'iicle rolls or tubescit-such thread to be inadvertently gathered up with sweepings and,tEhnown This practice is very wasteful in thread and no means isprovided in the large manufacturing establishments for either conservingthe thread by eliminating waste or maintaining the thread wound prior toits winding on the bobbin,

\Vith the foregoing considerations in 1924. Serial No. 710,238.

mind, the object of the present invention is to provide a neat, compactand efficient 13eceptacle or hold-er, one of which is adapted to beassociated with each machine and in a position convenient to the bobbin,though so conveniently positioned that it will not become an obstructionto the operator of the machine. A roll or tube of thread is adapted tobe housed within the casing which'is provided with outlet reaching intopro-X- iinity with the bobbin o f the machine and the thread is threadedthrough this outlet and only ashortend thereof normally protrudestherefrom. When it is desired to thread a bobbin, this short end iscarried to the bobbin, secured theretoand the winding convenientposition for winding the next bobbin. 7

At all times, however, the roll or tube of the thread is housed withinthe casingand maintained in clean condi on and in such form as topreclude tangiingor wasting of the thread.

The casing is so formed as to enable a roll or tube of thread to bereadily introduced thereintowhen the roll or tube previously therein hasbeen exhausted.

In the pneferred practical form of the vention, the casing ofcylindrical ,form and is mounted on the under side of the table of amachine by means of a suitable bracket. Extending upwardly from thecasing is an outlet channel or passage which while being pulled from theroll and wound upon the bobbin.

The device is simple in construction, economical to manufacture andfulfills a long felt want in ,manufactories where large quantities-ofthread are used. The thread is kept cleanandwasting is precluded.

Features of the invention, other than those specified, will be apparentfrom the hereinaiter detailed description and claims, when read inconjunction with the accompanying drawings.

The accompanying drawings illustrate one practical embodiment of theinvention, but the construction therein shown is to be understood asillustrative, only, and not as defining the limits of the invention.

Figure 1 is a perspective View 01" the device of the present inventionshowing the casing in opened condition, and,

Figure 2 is an end elevation of the device showing the casing in closedposition and mounted on a table of a machine.

Referring to the drawings, 1 designates a cylindrical casing parteddiametrically in a vertical plane to divide the-section into two parts 23, which are hinged together as shown at a. @ne end or" the casing isclosed by a circular disc 5, one half of which is r' ly secured to thesection 2 and the remaining half of which is loose with respect to thesection 3, The opposite end of the casing maybe closed by a fiat plateor disc adapted to bear against the end of the sections 2 and 3 butunattached to either.

The casing is adapted to be mounted on the table 6 of the machine bymeans of a of any suitable form. This bracket 4 bracket is secured tothe section 2 of the casing and is adapted to be permanently fixed tothe table of the machine by means of screws or bolts 8.

Extending coaxially of the casing and rigidly fixed in the end plate 5thereof is a bolt or axle 9. This bolt is somewhat longer than thecasing and is adapted to extend through the perforation in the oppositeend plate of the casing and for an appreciable distance beyond this endplate. The bolt 9 provides a support for roll or tube of thread 10, thethread being wound upon a suitable carrier or bushing 11 adapted to litover the bolt 9 as shown in Figure 1. The desired tension may be apolied to the roll by means of a helical. spring 12 coiled about the endof the bolt 9 exteriorly of the nd plate of the casing and this springis placed under the desired tension by means of an adjustable collar 13adapted to be locked on the bolt in any desired position by means of aset screw 1 1. In lieu of the collar 13 however the end of the bolt maybe threaded and a nut screwed upon the bolt for the purpose of placingthe spring 12 under the desired tension.

Extending upwardly from the top of the 1g is an outlet duct 15 which atits base, where it joins the casing, is substantially equal in width tothe length of the casing, but from this point the duct tapers upwardlyto substantially circular section and bent preferably on the arc of acircle in the direction of the bobbin 16 of the associated machine. Thisbobbin is shown in dotted lines at 16. The outlet duct is dividedcentrally into two sections 17 and 18, the former of which is rigid withthe section 2 of the casing while the latter of which is rigid with thesection 3 of the casing. Moreover, the outlet duct terminates in anoutlet or guide tube 19, the free end of which extends into proximitywith the bobbin 16. This guide tube is mounted rigidly on the section 15of the outlet duct and once the casing is closed and the sections oi theoutlet duct in assembled relation, the free end of the outlet ductsection 18 will abut the rear end of the guide tube 19, so as to form aclosed passage from the interior of the casing to the outlet end of theguide duct 19.

When it is desired to position aroll of thread in the casing, the collar13 and spring 12 are removed and a roll thereupon passed over the bolt9. During this operation, the section 3 of the casing and the section 18of the outlet duct are swung back on the pivot 1 to permit thisoperation to be conveniently carried out. roll 10 is in position on thebolt 9, the free end or" the thread, designated in the drawings by thereference character 10, is led upwardly through the open side of thesection 17 and threaded through the guide tube 19, after which thecasing is closed. is to say, the section 3'is swung upwardly on thepivot 4 until the section 18 of the out let duct comes into faceabutting relation with the section 17 of the duct.

During this operation, the section 18 will 7 be gripped by springfingers 20 mounted on the section 17 and these spring fingers Willtightly maintainthe duct and casing in closed position. The underplate,not shown, is next applied to the openend of the casing andthereafter the spring 12 is placed over the end of the bolt and thecollar 13 brought into position and locked in placeby the set screw letto place the spring under the desired tension. The casing is made ofsuch length that the under plate will bear against the end of the rolland so that the tension of the spring may cause the under plate to varythe friction between the roll and said plate and thus place the threadas it is drawn through the guide tube 19 under the desired tension.

The parts are preferably made of sheet metal so that the end tube ismore or less resilient and properly permits of its operation.

At the conclusion of the operations described, a short length of threadis left hanging from the outer end or" the guide tube 19, so that when abobbin requires threading, this end may be lead to the bobbin, securedthereto and the threading op- After the thread That 7 eration carriedout. When this threading operation is concluded, the thread is cutadjacent the bobbin and a free end is left hanging from the end of thetube 19 ready for subsequent winding operation.

it will be apparent from the foregoing detailed description of theinvention that it is of marked utility for the purpose stated and thatit not only keeps the thread perfectly clean but also provides a housingand holder for the thread so that it is protected against unraveling ortangling with the resuit that there is no loss or waste.

The drawings show the invention in itsv preferred practical form, butthe invention is to be understood as fully commensurate with theappended claims.
